Glass granules (glass particles/crushed glass) is a
non-ferrous reusable blasting media. Due to the angular
shape
of the particles, this blasting media has a grinding,
stripping effect on the workpiece being treated. In
comparison
to glass beads, it is more aggressive, but still often
used for the same applications. Glass granules can also
be
used in combination with glass beads. Due to the
relatively low purchase cost, it is used mainly outside
or in areas
with continual blasting media loss.
